when \(\rho _q\longrightarrow 0\) , the horizon of black hole becomes
\(\rho _h=\frac{2(\rho _0+\rho _M)}{\sqrt{1+64j^2\rho _M^2}+}-\rho _0\) , as
obtained in [1]}. In case of \(\rho _q\longrightarrow 0\)  and
\(j\longrightarrow 0\) , we have \(\rho _h=\rho _M\)  which is consistent
with neutral squashed Kaluza-Klein black hole [2]}. You note
that the square root in relation  (REF ) constrains the values
of \(\rho _0\) , \(\rho _q\)  and \(j\) . In the case \(j=0\) , the permissive
regime is shown in Ref.[3]}. For any value of \(\rho _q\) 
there is allowed rang for \(\rho _0\) . Hence these parameters can not
select any value and when \(j\)  increases from zero, permissive regime
for \(\rho _q\)  and \(\rho _0\)  becomes more confined. We solved the above
coupled equations numerically and results are shown in figure 1. We
see that the outer horizon of black hole increases with the size of
extra dimension, \(\rho _0\)  and decreases with \(j\)  and \(\rho _q\) . Note
that two horizons of black hole coincide in especial values of
parameters, which in that case we have an extremal black hole.
